Setup
------------
- IdeaVim can be installed via `Settings | Plugins`.
See the [detailed instructions](https://www.jetbrains.com/help/idea/managing-plugins.html#).
- Use `Tools | Vim` in the menu to enable or disable vim.
- Use the `~/.ideavimrc` file as an analog of `~/.vimrc` ([learn more](#Files)). The XDG standard is supported, as well.
- Shortcut conflicts can be resolved by using:
- On Linux & Windows: `File | Settings | Editor | Vim` & `File | Settings | Keymap`,
- On macOS: `Preferences | Editor | Vim` & `Preferences | Keymap`,
- Regular Vim mappings in the `~/.ideavimrc` file.

<summary><strong>Suggested options</strong> (click to see)</summary>
Here is also a list of the suggested options from [defaults.vim](https://github.com/vim/vim/blob/master/runtime/defaults.vim)
```vim
" Show a few lines of context around the cursor. Note that this makes the
" text scroll if you mouse-click near the start or end of the window.
set scrolloff=5
" Do incremental searching.
set incsearch
" Don't use Ex mode, use Q for formatting.
map Q gq
```
</details>
You can read your `~/.vimrc` file from `~/.ideavimrc` with this command:
source ~/.vimrc
Also note that if you have overridden the `user.home` JVM option, this
will affect where IdeaVim looks for your `.ideavimrc` file. For example, if you
have `-Duser.home=/my/alternate/home` then IdeaVim will source
`/my/alternate/home/.ideavimrc` instead of `~/.ideavimrc`.
Alternatively, you can set up initialization commands using [XDG](https://specifications.freedesktop.org/basedir-spec/basedir-spec-latest.html) standard.
Put your settings to `$XDG_CONFIG_HOME/ideavim/ideavimrc` file.
IdeaVim Plugins
--------------------
See [doc/IdeaVim Plugins.md](https://github.com/JetBrains/ideavim/wiki/IdeaVim-Plugins)
Executing IDE Actions
---------------------
IdeaVim adds various commands for listing and executing arbitrary IDE actions as
Ex commands or via `:map` command mappings:
### Executing actions:
* `<Action>({action_id})`
* For the mappings you can use a special `<Action>` keyword. Don't forget the parentheses.
* E.g. `map gh <Action>(ShowErrorDescription)` <- execute hover on `gh`.
* :warning: Mappings to `<Action>` don't work with `noremap`.
If you know the case when it's needed, please [let us know](https://github.com/JetBrains/ideavim#contact-maintainers).
* `:action {action_id}`
* Execute an action by `{action_id}`. Works from Ex command line.
* Please don't use `:action` in mappings. Use `<Action>` instead.
### Finding action IDs:
* IJ provides `IdeaVim: track action IDs` command to show the id of the executed actions.
This command can be found in "Search everywhere" (double `shift`).

<img src="assets/readme/track_action_light.gif" alt="track action ids"/>
</picture>
</details>
* `:actionlist [pattern]`
* Find IDE actions by id or keymap pattern (E.g. `:actionlist extract`, `:actionlist <C-D`)
##### Examples:
```vim
" Map \r to the Reformat Code action
:map \r <Action>(ReformatCode)
" Map <leader>d to start debug
:map <leader>d <Action>(Debug)
" Map \b to toggle the breakpoint on the current line
:map \b <Action>(ToggleLineBreakpoint)
```
##### Some popular actions:
```
ShowHoverInfo - Quick Documentation and Error Description
QuickImplementations - Quick Definition
```
Vim Script
------------
IdeaVim can execute custom scripts that are written with Vim Script.
At the moment we support all language features, but not all of the built-in functions and options are supported.
Additionally, you may be interested in the
[Vim Script Discussion](https://github.com/JetBrains/ideavim/discussions/357) or
[Vim Script Roadmap](https://github.com/JetBrains/ideavim/blob/master/vimscript-info/VIMSCRIPT_ROADMAP.md).
### IDE specific options
You can evaluate the `has('ide')` function call and get `1` if it was called with IdeaVim or `0` if the function was called from Vim/NeoVim.
The option `&ide` contains the name and edition of your IDE, for example, "IntelliJ IDEA Ultimate Edition".
To see its value for the current IDE you are using, execute the `:echo &ide` command.
To write an IDE-specific configuration, use Vim's regexp match operators `=~?` (case-insensitive) / `=~#` (case-sensitive)
**Example config:**
```vim
" options and mappings that are supported by both Vim and IdeaVim
set nu
set relativenumber
if has('ide')
" mappings and options that exist only in IdeaVim
map <leader>f <Action>(GotoFile)
map <leader>g <Action>(FindInPath)
map <leader>b <Action>(Switcher)
if &ide =~? 'intellij idea'
if &ide =~? 'community'
" some mappings and options for IntelliJ IDEA Community Edition
elseif &ide =~? 'ultimate'
" some mappings and options for IntelliJ IDEA Ultimate Edition
endif
elseif &ide =~? 'pycharm'
" PyCharm specific mappings and options
endif
else
" some mappings for Vim/Neovim
nnoremap <leader>f <cmd>Telescope find_files<cr>
endif
```

IdeaVim tips and tricks
-------
- Use the power of IJ and Vim:
- `set ideajoin` to enable join via the IDE. See the [examples](https://jb.gg/f9zji9).
- Make sure `ideaput` is enabled for `clipboard` to enable native IJ insertion in Vim.
- Sync IJ bookmarks and IdeaVim global marks: `set ideamarks` (works for marks with capital letters only)
- Check out more [ex commands](https://github.com/JetBrains/ideavim/wiki/%22set%22-commands).
- Use your vim settings with IdeaVim. Put `source ~/.vimrc` in `~/.ideavimrc`.
- Control the status bar icon via the [`ideastatusicon` option](https://github.com/JetBrains/ideavim/wiki/%22set%22-commands).
- Not familiar with the default behaviour during a refactoring? See the [`idearefactormode` option](https://github.com/JetBrains/ideavim/wiki/%22set%22-commands).
Some facts about Vim
-------
Let’s relax and have some fun now! Here are a few things we've found interesting during development
and would like to share with you.
- There are no such commands as `dd`, `yy`, or `cc`. For example, `dd` is not a separate command for deleting the line,
but a `d` command with a `d` motion.
Wait, but there isn't a `d` motion in Vim! That’s right, and that’s why Vim has a dedicated set of commands
for which it checks whether the
[command equals to motion](https://github.com/vim/vim/blob/759d81549c1340185f0d92524c563bb37697ea88/src/normal.c#L6468)
and if so, it executes `_` motion instead.
`_` is an interesting motion that isn't even documented in vi, and it refers to the current line.
So, commands like `dd`, `yy`, and similar ones are simply translated to `d_`, `y_`, etc.
[Here](https://github.com/vim/vim/blob/759d81549c1340185f0d92524c563bb37697ea88/src/normal.c#L6502)
is the source of this knowledge.
- `x`, `D`, and `&` are not separate commands either. They are synonyms of `dl`, `d$`, and `:s\r`, respectively.
[Here](https://github.com/vim/vim/blob/759d81549c1340185f0d92524c563bb37697ea88/src/normal.c#L5365)
is the full list of synonyms.
- You can read a [post](https://github.com/JetBrains/ideavim/wiki/how-many-modes-does-vim-have) about how modes work in Vim and IdeaVim.
- Have you ever used `U` after `dd`? [Don't even try](https://github.com/vim/vim/blob/759d81549c1340185f0d92524c563bb37697ea88/src/ops.c#L874).
- A lot of variables that refer to visual mode start with two uppercase letters, e.g. `VIsual_active`. [Some examples](https://github.com/vim/vim/blob/master/src/normal.c#L17).
As mentioned [here](https://vi.stackexchange.com/a/42885/12441), this was done this way to avoid the clash with X11.
- Other [strange things](https://github.com/vim/vim/blob/759d81549c1340185f0d92524c563bb37697ea88/src/ex_docmd.c#L1845) from vi:
* ":3" jumps to line 3
* ":3|..." prints line 3
* ":|" prints current line
- Vim script doesn't skip white space before comma. `F(a ,b)` => E475.
- Fancy constants for [undolevels](https://vimhelp.org/options.txt.html#%27undolevels%27):
> The local value is set to -123456 when the global value is to be used.
- Vi (not Vim) is a POSIX standard, and [has a spec](https://pubs.opengroup.org/onlinepubs/9699919799/utilities/vi.html)! Vim is mostly POSIX compliant when Vi compatibility is selected with the `'compatible'` option, but there are still some differences that can be changed with `'copoptions'`. The spec is interesting because it documents the behaviour of different commands in a stricter style than the user documentation, describing the current line and column after the command, for example. [More details can be found by reading `:help posix`](https://vimhelp.org/vi_diff.txt.html#posix).
